build-systems: gnu: Export %default-gnu-imported-modules and %default-gnu-modules.

Until now users would have to cargo cult or inspect the private
%default-modules variable of (guix build-systems gnu) to discover which
modules to include when extending the used modules via the #:modules argument.

The renaming was automated via the command:

  $ git grep -l %gnu-build-system-modules
    | xargs sed 's/%gnu-build-system-modules/%default-gnu-imported-modules/' -i

* guix/build-system/gnu.scm (%gnu-build-system-modules): Rename to...
(%default-gnu-imported-modules): ... this.
(%default-modules): Rename to...
(%default-gnu-modules): ... this.  Export.
(dist-package, gnu-build, gnu-cross-build): Adjust accordingly.

gnu: git: Invert inheritance relationship.

It's simpler to add features on top of a minimal variant than to remove them,
and helps avoiding mistakenly changing git-minimal, which has many dependents.

* gnu/packages/version-control.scm (git-minimal): Move above git and severe
inheritance.  Remove input label.  Repatriate most fields from...
(git): ... here.  Define as package/inherit to inherit from git-minimal.
Extend minimal values instead of overriding them whole.
